Based on the provided code, it seems that you are trying to create a drake::drake_plan with multiple targets and transforms. Here’s an example of how you can structure your plan without any transforms: library(drake) plan <- drake_plan( # Target 1 target = "a", fn1 = function(arg1, arg2) { print("Function 1 executed") }, # Target 2 target = "b", fn2 = function(arg1) { print("Function 2 executed") }, # Target 3 target = "d", fn3 = function(arg1) { print("Function 3 executed") } ) # Desired plan for the run target run_plan <- tibble( target = c("a", "b", "d"), command = list( expr(fn1(c("arg11", "arg12"), c("arg21", "arg22"))), expr(fn2(c("arg11", "arg12"))), expr(fn3(c("arg11", "arg12"))) ), path = NA_character_, country = "1", population_1 = c(rep("population_1_sub1", 2), rep("population_1_sub2", 2)), substudy = c(rep("sub1", 2), rep("sub2", 2)), adjust = c(rep("no", 2), rep("yes", 2)), sex = c(rep("male/female", 4)), pedigree_1 = c(rep("pedigree_1_sub1", 2), rep("pedigree_1_sub2", 2)), covariable_1 = c(rep("covariable_1_sub1", 2), rep("covariable_1_sub2", 2)), model = c("x", "y", "z") ) config <- drake_config(plan, run_plan) vis_drake_graph(config, targets_only = TRUE) As for the issue with map not understanding .

Parsing JSON Lists of Dicts to Pandas DataFrames ===================================================== As data scientists and engineers, we frequently encounter various formats for exchanging data. In this post, we will explore how to efficiently parse a specific type of JSON data into a Pandas DataFrame. Background: Working with Nested JSON Data The provided JSON data is in the format of a list of dictionaries, where each dictionary represents an individual record and contains other lists of dictionaries as values.

Fuzzy Grouping in R: A Deep Dive into Approximate Clustering R is a powerful programming language and software environment for statistical computing and graphics. One of its strengths lies in data manipulation, analysis, and visualization. However, when it comes to grouping values based on approximate ranges, the built-in functions may not provide the desired results. In this article, we’ll delve into the world of fuzzy clustering in R, exploring what fuzzy grouping entails, available methods for achieving this, and some practical examples.

Removing Rows Based on Decreasing Column Values In this article, we will explore a common problem in data analysis and manipulation. Specifically, we’ll discuss how to remove rows from a DataFrame where the values in certain columns decrease at any point. Introduction When working with large datasets, it’s essential to identify patterns and trends that can help us make informed decisions. One such pattern is when column values decrease over time or across different groups.

Implementing a Login Screen Before a TabBar View in iOS In this article, we will explore how to add a login screen before a tab bar view in an iOS application. We will delve into the details of the process and provide examples to help you understand the concepts involved. Overview of iOS App Navigation Before we dive into implementing the login screen, it’s essential to understand how an iOS app navigates between different views.

Handling Dynamic Group By Orders in SQL Server 2008 Introduction SQL Server 2008 provides several ways to perform dynamic queries, but handling group by orders can be a challenge. In this article, we will explore different approaches to achieve dynamic group by orders based on user’s selection. Understanding the Problem The problem at hand involves changing the column order in the group by line of a SQL query based on user’s demand.

Optimizing SQL Queries: A Deep Dive into Aggregation and Joining Introduction As a programmer, one of the most common challenges you’ll face is optimizing your SQL queries to achieve faster performance. With increasing amounts of data, slow query times can significantly impact application usability and user experience. In this article, we’ll explore how to optimize SQL queries by aggregating data before joining tables, reducing the number of joins required. Understanding Aggregate Functions Aggregate functions are used to perform calculations on a set of values that are returned in a single output value.

Understanding Pandas Timestamps and Concatenating Hours with Dates in Python ===================================================== As a data analyst or scientist working with data in Python, you often encounter the need to manipulate and analyze timestamps. In this article, we’ll explore how to concatenate hours with dates using pandas, a powerful library for data manipulation and analysis. Introduction to Pandas Timestamps Pandas is an essential library in Python for data manipulation and analysis. One of its key features is handling timestamp data.

Comparing Abbreviated Words Based on Mapping File in Pandas and Python In this article, we will explore how to compare abbreviated words based on a mapping file using pandas and Python. We will use the following steps: Create two dataframes: df and df_map. Use the set_index method on df_map to convert it into a dictionary. Join the keys of the dictionary with a pipe (|) character to create a regular expression pattern that can match any of the abbreviations.

Understanding the pandas strftime Function and the %j Format Specifier When working with date data in pandas, formatting dates can be crucial for extracting specific information or performing calculations. One of the most commonly used format specifiers in pandas is %j, which represents the day of the year. In this article, we will delve into the details of how strftime works, particularly with the %j format specifier. Introduction to the %j Format Specifier The %j format specifier is used to represent the day of the year as a zero-padded decimal number.
